The other day I was saying, "Goody, goody, gumdrops," and my friend, who is a non-native speaker of English, asked what I meant. It was easy to explain that was a phrase meaning delight that originated with the happy prospect of getting candy. But it was a bit harder to explain that it is also used sarcastically which is how I usually use it. That got me thinking about other idioms we use everyday and never think twice about.
So in the theme of sayings starting with G, I here are a few more:
Go against the grain means go against natural tendencies. It refers to going against the grain when working with wood which is hard work. Shakespeare popularized this phrase.
Go fly a kite go away, stop bothering me. Kite flying is an activity that could keep some busy and away from you.
Go Bananas means go crazy. This came from the association of bananas with monkeys and monkeys are thought to have silly, uncontrolled behavior.
Gone to pot means that something is ruined. This came from the 1500's and refers to animals that couldn't do work, so they were more likely to end up in the cooking pot.
Goody-Two-Shoes means person who is trying to be perfect. This saying comes from a nursery tale in the mid 1700's about a girl who only had one shoe and who was then given another one. She showed off her shoes saying, "Two shoes."
Grasping at straws means to try something with little hope of it succeeding. This saying was popular by the 1600s and referred to someone drowning who only had had reeds along the banks to grasp onto.
Green with envy means extremely jealous. Shakespeare popularized green with the envy when he referred to it as the green sickness in Antony and Cleopatra.
